Feature request: Add project level branch restrictions

[act-mreeves]

Currently https://registry.terraform.io/providers/DrFaust92/bitbucket/latest/docs/resources/branch_restriction only supports repo level branch restrictions. However, bitbucket provides a way to do this at the project level: https://support.atlassian.com/bitbucket-cloud/docs/configure-a-projects-branch-restrictions/

I am guessing that might require a new bitbucket_project_branch_restriction resource.

I admit I don't see an obvious way to do this via the API when I look at:

• https://developer.atlassian.com/cloud/bitbucket/rest/api-group-branch-restrictions/#api-repositories-workspace-repo-slug-branch-restrictions-post
• https://developer.atlassian.com/cloud/bitbucket/rest/api-group-projects/#api-workspaces-workspace-projects-post

Im almost certain this is not public API. been looking at this on and off for a while and couldnt make it work via API 🤷
